Summary: A summary and aide memoire of Bash parameter expansion methodsSeries: Bash ScriptingSource: http://hackerpublicradio.org/eps.php?id=1648Bash parameter manipulation I'm a great fan of using the Linux command line and enjoy writing shell scripts using the Bash shell. BASH (or more usually Bash or bash) is the name of a Unix shell. The name stands for Bourne Again SHell, which is a play on words. Bash is an extension of the shell originally written by Stephen Bourne in 1978, usually... Topics: Bash, script, parameter, variable
Children can link facts and events into integrated beliefs. This ability of the mind to combine facts to form higher-order Gestalts is central to many cognitive activities, including problem solving, analogical reasoning, and creative thought. In fact, it is central to the abduction of meaning: the creation of a self-sustaining pattern of ordered facts that are combined in the larger Gestalt. Abduction has mostly escaped experimental investigation, possibly because it often emerges instantly... Topics: Abduction, Reasoning, Nonlinear Dynamics, Constraints, Parameter Dynamics
The issues regarding the functioning and growth of an ideal economic society is the subject of investigation here. One basic guideline for such a society is that it must have total control over its economics and that money cannot drive such a society from pillar to post. The equal right of every individual over the basic amenities to live and grow and equal right of every individual over the resources, ensuring no misuse of the society's resources may be taken care of by controlling the market...

Steam turbine blades are the most important component of the thermal power plant. Most of the research work on creep estimation is done on the high pressure or intermediate pressure turbines blades. The main aim of this study is to estimate the creep life of 210 MW low pressure steam turbine blade. In first stage the three dimensional model of the blade was prepared in the PRO-E then this model is imported in ANSYS-14.5 for finite element analysis. Maximum stress and maximum deformation can be... Topics: Creep, Larson Miller Parameter, Stress Analysis, Turbines.
Water is one of the most vital natural resources used not only for direct consumption purposes but also as an input in the process of production in different sectors of the economy of which agriculture is the most important. Sustainable water management in a river basin requires knowledge of the water availability and water requirements of the basin in the present and future for various purposes. Evapotranspiration is a key component of water resource management influencing the water demands of... Topics: Evapotranspiration, Climate Parameter, Remote Sensing and GIS
The hospital cardiac patient monitoring industry is evolving rapidly and is becoming increasingly competitive as more parameters are monitored and integration with the electronic patient record occurs. This is the basis on which vendor share shifts, with Philips gaining share in recent years. Companies with substantial resources are poised to enter the market, probably through acquisition. Vendors are poised to face increased competition even as market consolidation occurs. Shortness of breath...

Detection of breast cancer in its early stage is very important in the field of medicine. Optimal Contrast Enhancement is essential for the detection of mass and micro calcification in mammogram images. The standard histogram equalization is effective and simple method for contrast enhancement but for medical images most of the time it produces excessive contrast enhancement due to lack of control for the level of enhancement. In this paper image enhancement is considered as an... Topics: Optimization, Enhancement parameter, Parameter Tuning, Histogram Equalization, Local Contrast...
In general, yaw control of aircraft plays a major role. It is controlled by rudder deflection by creating side force with help of rudder pedals. The aircraft yaw is controlled by several methods such as Fuzzy logic, linear quadraticcontroller (LQR), optimal pole placement method. These methodologies achieved only the transient response, but failed to obtain the steady state response. There are some cases, where the steady state response is necessary. In this research paper, we propose a new... Topics: Aircraft, Flight Control, Two Parameter, Yaw, Rudder, Disturbance Suppression

Partitioning of two amino acids ( DL-alanine and hexaglycine) were measured in dextran + poly( ethylene glycol)+ water two- phase system. The coefficient for partition of DL-alanine and hexaglycine were correlated by using the osmotic viral equation. The phase interaction or partitioning coefficientin the equation can be calculated by hydrophilic group’s parameters which gives in fairly good agreement with the experimental data on change in concentration at 293.15Kat room pressure.

Power law distribution appears in several scientificfields such as physics, earth science, economics, social science andmany others. This paper illustrates new practical criteria forinferential statistics involving power law and, namely forestimation of power law distribution exponent and its confidenceinterval. To calculate this latter interval new expressions, inclosed form, are derived. This methodology has been comparedwith classical least squares method and that of maximumlikelihood,...

The genetic regulatory network, which is constructed fromthe time‐courses data sets, is always described as highlynonlinear differential equations. Mathematical andcomputational modeling technologies focus on efficientlyidentifying the parameters of the nonlinear dynamicbiological system. Various derivative‐free and derivativebasedoptimization technologies have been proposedrecently to infer the parameters of the S‐type geneticregulatory networks (S‐systems). The S‐system is...

In this paper, a novel dual estimation methodology is developed for both time-varying parameters and states of a nonlinear stochastic system based on the Recursive Prediction Error (RPE) concept and Particle Filtering (PF) scheme. Our developed methodology in based on a parallel implementation of stateand parameter estimation filters as opposed to using a single filter for estimating the augmented states and parameters. The convergence and stability of our proposed dual estimation strategy are... Topics: Particle filter, parameter estimation, fault diagnosis, dual estimation
This work proposes the use of both the wavelet transform and the curvelet transform for denoising of images corrupted by AWGN. The wavelet reconstruction contains artifacts along the edges in an image. These edges can be captured efficiently by curvelets but curvelets are challenged by smooth regions where artifacts are largely visible. The desirable algorithm for denoising a noisy image should preserve the fine structures in the image and at the same time should not introduce artifacts. In...

Use of rock‐beds with bed elements having geometricalshapes and sizes to result in temperature stratification for theimprovement of performance of solar air heater has beenproposed by several investigators. However, this enhancedefficiency is accompanied by substantial increase in pressureloss, so the solar energy storage system should be optimizedin such a way that there is maximum thermal gainaccompanied by minimum possible pressure losses.
